So you’ve spent hundreds of hours punching trees and building dirt huts, and now the vanilla version of Minecraft feels a bit... empty. It happens to everyone. You see these massive YouTubers playing with dragons, complex machinery, or hyper-realistic shaders, and you want in. But figuring out how to do mods on Minecraft PC can feel like trying to defuse a bomb if you aren't a technical person. Honestly, it's simpler than it looks, but there are about a dozen ways to mess it up if you don’t pick the right starting point.
The first thing you have to understand—and this is where most people trip up immediately—is that there isn't just one "Minecraft." If you’re playing on a PC, you either have Bedrock Edition (the one from the Microsoft Store) or Java Edition (the original version). If you want the real, game-changing mods like RLCraft or Create, you need Java Edition. Bedrock has "Add-ons," which are cool, but they aren't true mods in the way most people mean.
Picking Your Poison: Forge vs. Fabric
Before you download a single file, you have to choose a mod loader. Think of a mod loader as the foundation of a house. You can't put a roof on a house that doesn't exist. In the world of Java Edition, the two big players are Forge and Fabric.
Forge has been around since the dawn of time. Well, since 2011. It’s the heavy hitter. Most of the massive, complex modpacks that change every single mechanic in the game run on Forge. It’s robust, but it can be a bit slow to load. On the flip side, you have Fabric. Fabric is the new kid on the block—lightweight, fast, and often updated much quicker when Mojang releases a new game version.
Here’s the catch: they don’t play nice together.
If you install a mod designed for Fabric into a Forge setup, your game will crash before it even reaches the title screen. You have to commit to one for each specific profile you play. Most veterans keep both installed for different playthroughs. For your first time, I usually suggest Forge just because the library of compatible mods is staggering, though Fabric is catching up fast with performance-boosting mods like Sodium and Iris.
How to Do Mods on Minecraft PC the Easy Way
If you’re someone who hates digging through file folders and dragging things into %appdata%, use a launcher. Seriously. Using the standard Minecraft launcher for mods is like trying to eat soup with a fork. It’s possible, but why would you do that to yourself?
The CurseForge App
The CurseForge app is basically the gold standard for beginners. It’s owned by Overwolf now, and while some people find the app a bit bloated, it handles all the heavy lifting. You just search for a modpack, click "Install," and it handles the versioning, the dependencies, and the file placement.
- Download the CurseForge app.
- Select Minecraft from the dashboard.
- Click "Create Custom Profile" if you want to pick individual mods, or "Browse Modpacks" to find a pre-made experience.
- Hit Play.
It’s that simple. The app creates a separate instance of the game, so your vanilla worlds stay safe and clean. No risk of accidentally deleting your five-year-old survival map.
Prism Launcher (For the Power Users)
If you want something cleaner and faster, check out Prism Launcher. It’s an open-source fork of the old MultiMC. It’s incredibly lightweight and lets you manage dozens of different Minecraft versions and mod setups without the clutter of ads or extra software. It’s what I personally use because it gives you total control over how much RAM you’re allocating to the game—a crucial step we’ll talk about in a minute.
The Manual Method (The "Old School" Way)
Maybe you don't want an extra app. Maybe you want to understand the guts of the machine. To learn how to do mods on Minecraft PC manually, you need to be comfortable with your file explorer.
First, go to the official website for either Forge or Fabric. Download the "Installer" version. When you run it, it’ll ask if you want to install the "Client" or "Server." You want the Client. Once that finishes, open your official Minecraft Launcher. You should see a new profile in the bottom left corner named after the loader you just installed.
Now comes the magic folder. Press Windows Key + R on your keyboard. Type %appdata% and hit enter. Find the .minecraft folder. Inside, you should see a folder named mods. If it’s not there, just right-click and create a new folder named exactly that: mods (all lowercase).
This is where you drop your .jar files. When you find a mod on a site like Modrinth or CurseForge, you download the file and just slide it into that folder.
Why Your Game Just Crashed
It happened, didn't it? You hit play and got a "Code 1" error.
Nine times out of ten, this is because of Dependencies. Many mods don't work alone. For example, a lot of decorative mods require a separate file called "Architectury API" or "Cloth Config API." If you read the mod description page carefully, it will usually list "Required Dependencies." You have to download those and put them in your mods folder too. It’s annoying, but it’s the price of a custom experience.
Managing Your PC’s Resources
Modded Minecraft is a resource hog. It eats RAM like it’s at an all-you-can-eat buffet. By default, the Minecraft launcher only gives the game 2GB of RAM. That’s enough for vanilla, but if you’re running a 200-mod pack, your game will stutter, freeze, and eventually die.
You need to "Allocate" more RAM.
In the Minecraft Launcher, go to the "Installations" tab. Hover over your modded profile and click the three dots, then "Edit." Click "More Options" at the bottom. You’ll see a line of text called "JVM Arguments." It looks scary, but you only care about the very first part: -Xmx2G.
Change that 2G to a 4G or an 6G.
Do not give it all your RAM. If your computer has 16GB of RAM, give the game 6GB or 8GB. If you give it too much, your Windows operating system won't have enough room to breathe, and your whole computer will start lagging. It’s a delicate balance.
Finding the Best Mods in 2026
The scene has changed a lot lately. While old classics like IndustrialCraft and Thaumcraft are still around in various forms, the community has shifted toward "Vanilla Plus" mods. These are mods that feel like they could have been made by Mojang.
- Alex’s Mobs: Adds dozens of animals with unique AI. It makes the world feel alive.
- Create: This is the big one. It adds mechanical power, gears, and conveyor belts. It’s probably the most visually impressive mod ever made.
- Sodium: If you have a low-end PC, this is mandatory. It re-writes the rendering engine to give you a massive FPS boost.
- Waystones: Because walking 10,000 blocks back to your base is objectively boring.
Staying Safe and Avoiding Malware
This is the serious part. There was a major security scare a while back called "Fractureiser." Malicious code was injected into some popular mods on various hosting sites. While the major platforms have cleaned it up, you still need to be careful.
Only download mods from Modrinth or CurseForge.
Never, ever download a mod from a site that looks like "https://www.google.com/search?q=MinecraftMods-2026-Free-Download.com" or those weird "repost" sites. These sites often steal modders' work and bundle it with adware or worse. Modrinth is generally preferred by the developer community these days because it has a cleaner UI and pays the creators better, but CurseForge still has the largest archive of older mods.

Addressing the Versioning Headache
Minecraft updates constantly. Mojang is always adding new blocks and mobs. This is great for the game, but it’s a nightmare for modders.
A mod made for version 1.20.1 will almost never work on version 1.21. Unlike some other games where mods are "forward compatible," Minecraft mods are very specific to the version they were built for. If you find a cool mod you love, check which version it supports before you build your whole game around it. Most of the "big" modding happens on "LTS" (Long Term Support) versions. Currently, 1.12.2, 1.16.5, 1.18.2, and 1.20.1 are the most popular versions for mods. If you stay on those versions, you’ll find the most variety.
Essential Next Steps for Your Modded Journey
Once you've successfully launched the game with mods, your work isn't quite done. To truly enjoy the experience without constant headaches, you need to set up a few "Quality of Life" features.
First, get a mod called JEI (Just Enough Items). Without it, you won't know how to craft anything in your new mods. JEI adds a searchable sidebar to your inventory that shows every item in the game and exactly how to make it. It’s basically the Bible for modded players.
Second, consider your backup strategy. Modded worlds are inherently more fragile than vanilla ones. A single update to a mod can occasionally corrupt a chunk or delete specific items.
Back up your world folder every time you add or remove a mod.
Go into your .minecraft folder, find saves, and copy your world folder to a different location on your hard drive. If something breaks, you’ll be glad you spent the thirty seconds to do it.

Finally, keep an eye on your "Logs" folder. If your game crashes, there will be a file in .minecraft/crash-reports. Open it with Notepad. Scroll down to the "Details" section. It usually says something like "X Mod failed to load." This is your best tool for troubleshooting. Instead of panicking, just read the log—it usually tells you exactly which file is causing the problem.
Now that you know the basics of how to do mods on Minecraft PC, the best thing to do is start small. Don't try to install 300 mods at once. Start with a loader, add five mods you like, make sure it runs, and then expand from there. It’s a rabbit hole, but it’s one that makes the game feel brand new again.
